Configuring the hardware
All hardware configuration options on the PCI-DAS1002 are software controlled. You can select some of the
configuration options using InstaCal, such as the analog input configuration (16 single-ended or eight
differential channels), and the source for the two independent counters. Once selected, any program that uses
the Universal Library will initialize the hardware according to these selections.
For general information regarding analog signal connection and configuration, refer to the Guide to Signal
Connections (available on our web site at
www.mccdaq.com/signals/signals.pdf ).
Differential input mode
When all channels are configured for differential input mode, eight analog input channels are available. In this
mode, the input signal is measured with respect to the low input. The input signal is delivered through three
wires:
 The wire carrying the signal to be measured connects to CH# IN HI.
 The wire carrying the reference signal connects to CH# IN LO.
 The third wire, typically a system ground, connects to LLGND.
Single-ended input mode
When all channels are configured for single-ended input mode, 16 analog input channels are available. In this
mode, the input signal is referenced to the board's signal ground (LLGND). The input signal is delivered
through two wires:
 The wire carrying the signal to be measured connects to CH# IN HI.
 The second wire connects to LLGND.
